well here's a bunch of no fun - it compiles but it won't load. I know it works in studio with avrisp on com4 so I've selected "attiny2313at8.upload.protocol=avrispv2" and port com 4. I get the first set of gibberish. Tried using "upload using programmer" with programmer set to avrisp and i get the second set of gibberish - which looks a bit more informative at least.

The Serial class in tiny cores is ouput only, so you'll need to use another serial library to receive.

thanks: is this true for the 2313 as well? It might just be easier for me to use avr studio. I have a good sized arduino program that I want to port though so I'd much rather stick with the IDE.

also: how do i map which pin is where for the various processors?

Even though the 2313 has a UART, I don't think tiny cores uses it. Better check the code to be sure though.For mapping the pins you have to change the TinyDebugSerial library code. Here's another thread discussing serial options:http://forum.arduino.cc/index.php?topic=207467.0
